All these years and never used WASD once in G1…L/ctrl + up/down/left/right instead. Strafe is L/alt + /l/r.

So…i would imagine if all witcher keys are mappable i could omit the WASD keys completely and play almost identical to G1. But then engaging onto 3D objects could be a problem like you suggest, my guess is the good old focus highlight method will come into play…….we will see.
